RE: Ceiling Speakers - Advice Needed

["White, Peter" <peter.white@xxxxxxxxxxxxx>]

Not really.  If you just have the volume at normal 'background or
listening
levels' then there's no sound intrusion at all. If you crank it up to quite
a loud level (subjective, but lets say loud enough to not hear the kids
wrecking another part of the house!) then you can hear a dull thud on the
bass, but still not much.   The construction, working from the floor down,
is 18mm OSB, 50mm Rockwool, 230mm void then 10mm Fermacell into which the
speakers are mounted.  Plus I stuffed in more Rockwool above most of the
speakers which is excellent at killing sound travel, but aside from that, I
didn't do any other sort of containment or bracing.

Pete,

A couple of questions. Does the sound travel to the rooms above? Did you
box
the speakers in any way?
